The Digital line is an extension of Swan Song’s power supply and analog circuitry capabilities. Current DACs and ADCs are at the point where the most gains can be found in the areas of execution, power supplies, and analog amplification/buffering. Products include:
- 192kHz 24 bit Digital to Analog Converter with Preamp
- 192kHz 24 bit Analog to Digital Converter
Digital to Analog Converter Preamp - $2600 with power supply
The Digital to Analog Converter Preamplifier combines a 192kHz DAC, Preamplifier, and dedicated headphone amplifier. The DACP has four 192kHz inputs, fixed and variable outputs, a volume control, and a separate headphone amplifier.
The DACP design focuses on keeping digital noise out of the analog signal. Clean separate power "supplies", power up on demand logic, only the best components, and years of producing low noise phono preamps combine to create an exceptionally clean non-“metallic” DACP.
Headphone and speaker based listening differ in the amount of space available to develop full stereo imaging. This “lack of space” led to the development of crossfeed to adjust the left right output signals in order to create a “stereo center channel” from headphones. To aid with headphone "stereo imaging", the DACP contains an adjustable crossfeed circuit. Turn the “xfeed” knob to the left and pure stereo sound is sent out the headphone jack. Turn the “xfeed” knob to the right and the crossfeed circuitry is engaged. The amount and level of crossfeed is determined by the amount of “xfeed” knob rotation to the right.
Whether used as a preamp or as a headphone amp, the analog focused DACP blurs the lines between digital and analog.

ADC is the “other side of the coin”. The ADC begins with the TI PCM1861 ADC and Cirrus 8406 output chip. Variable clocking along with Swan Song’s Phono and Power supply technology combine to produce an ADC capable of capturing all the nuances of an analog recording. Adding in the convenience of a volume control with a peak level indicator ensures that conversion is done without clipping.
The ADC and DACP combination are so clean that combined with the in house Wein Bridge sine wave generator they only increase the distortion from .0025% to .006%
Both products use the same European natural aluminum anodized chassis as in the phono product line. Do not let the small chassis fool you into thinking less of this little power house. It has successfully transmitted data via fiber optic at a distance of 50 feet.
Here are two sample clips from the SE Phono and the ADC using a Sumiko Pearl MM cartridge.
